Ironically, it’s Homer’s own desire to find von Braun that results in his not seeing him at all—if he’d only stayed put, von Braun would have come to him. There’s also some metaphorical significance to this fact, as Homer sometimes tries a little too hard to succeed, cutting himself off from his peers and assuming that he has to do everything himself. Homer’s success at the science fair is the result of his own hard work, but also the support of his friends, especially Orville—indeed, if it hadn’t been for Orville, Homer wouldn’t have his medal.
